The Development of an Instrument to Measure Preservice Teachers' Attitudes about Discourse in the Mathematics Classroom

This study explored the themes that comprise preservice teachers' attitudes regarding discourse in the K‐12 mathematics classroom. The initial development of the theory underlying preservice teachers' attitudes regarding mathematical discourse is documented through the development of a 5‐point Likert instrument. Analysis of the Preservice Teachers' Attitudes About Discourse in the Mathematics Classroom (PADM) Instrument (N – 277) resulted in three reliable factors: Promoting Mathematical Reasoning (α₁= .85), Examining Complex Mathematical Concepts (α₂= .81), and Valuing Students' Mathematical Ideas (α₃= .85). These results suggest a framework that mathematics educators can employ to address preservice teachers' attitudes regarding discourse in an effort to support their implementation of reform‐based discourse in the teaching of mathematics in their future classrooms.
